Question

错误：

 AttributeError at /
'UserForm' object has no attribute 'get'

我无法调试此错误！我无视了我的代码很多次，但无法理解在哪里生成错误。请帮助我。提前致谢。

froms.py

class UserForm(forms.Form):
    username = forms.CharField()
    email = forms.EmailField()
    password1 = forms.PasswordInput()
    password2 = forms.PasswordInput()


    def clean(self):
        password1 = self.cleaned_data['password1']
        password2 = self.cleaned_data['password2']
        if password1 != password2:
            raise forms.ValidationError('Password Should Match')
        return self.cleaned_data

views.py

def userview(request):
    if request.method == 'POST':
        form = UserForm(request.POST)
        if form.is_valid():
            username = form.cleaned_data['username']
            email = form.cleaned_data['email']
            password1 = form.cleaned_data['password1']
            user = User(username=username,email=email,password =password1)
            user.save()
            return HttpResponse('User Created')
    else:
        form = UserForm()
    return render(request,'home.html',{'form':form})

模板 home.html

<form method="post" id="post-form">
    {% csrf_token %}
    {{form.as_p}}
<input type='submit' value ='ok'>
</form>

项目级urls.py

from django.contrib import admin
from django.urls import path,include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('',include('useradd.urls'))
]

应用级urls.py

from django.urls import path
from . import views
urlpatterns =[
    path('',views.UserForm,name = 'useradd')

]

作为指示，我已经提供了对该错误的完整追溯。我认为我已经在views.py中定义了post方法，当方法未发布时，它将访问该函数的其他部分。但是仍然不明白为什么会发生这样的错误。

Answer 1

在您的网址中出现问题。而不是视图，您正在将表单传递给url，应该是这样的：

urlpatterns =[
    path('',views.userview,name = 'useradd')

]

Answer 2

这是因为UserForm类没有称为get的方法或变量。您需要先定义一个。

'AttributeError'：对象没有属性'get'
